CHAIR.

Specification of Letters Patent.

Patented Dec. 19, 1995.

Application filed March 1, 1904. Serial No. 196,107.

To all whom it may concern:

Be it known that I, CAsPAR M.WAGNER, residing at Chicago, -in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Chairs, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to improvements in chairs, and has for its objectto produce a strong and durable folding chair that can be readily andquickly opened and closed and when closed or folded will occupy but verylittle space. I accomplish this object as illustrated in the drawingsand hereinafter specifically described.

That which I believe to be new will be pointed out in the claim.

In the drawings, Figure l is a side elevation. Fig. 2 is a rearelevation, and Fig. 3 is a side elevation with the chair in its closedor folded position.

Referring to the several figures of the drawings, in which correspondingparts are indicated by the same reference-letters, A indicates aseat-frame rectangular in shape, which may be provided with a centralseat-section of wood or leather or other desired material.

B C indicate a pair of supporting-legs for each side of the chair, theleg B of each pair being secured at its upper end to the side of theseat-frame near the forward edge of such seat-frame by a pivot a.

- 6 indicates a pivot connecting the two legs B and (J together.

D indicates a back-frame secured by pivots c to the sides of theseat-frame A near the rear edge of such seat-frame. As shown, the sidebars of the back-frame D are extended downwardly a considerable distancebelow the seatframe, and their lower ends come in contact with and bearagainst the upper edges of the legs B.

It will be observed that the legs C of each pair are longer than thelegs B, which is to enable such legs C to project some distance abovethe seat-frame and alongside the outer faces of the side bars of theback-frame, to which side bars they are attached by pivots d.

6 indicates an ordinary cross-bar secured between the side bars of theback-frame just below the seat-frame, and f g indicate similarcross-bars secured between the legs B.

Each side bar of the back-frame is provided I with a widened portionjust above the seatframe, and at these widened portions the said sidebars are so curved as to bring the forward edges of theirdownwardly-extending parts considerably in advance of the forward edgesof their upper portions, and by this construction I am enabled to effecta'very close folding of the chair, as a whole much closer, in fact, thanif the forward edges of these bars were straight from end to end, for,as is evident from an inspection of Fig. 3, where the chair is shown inits folded position, the curving referred to permits the upper portionof the side bars of the back-frame to lie close against the pair of legsB, while the remaining portion of the side bars lies directly in linewith the legs B and C.

When the chair is in use, it is evident that the greater the pressurethat is brought to bear against the back-frame the greater will be theforce exerted by the lower portions of the side bars of the back-frameagainst the legs B, such legs acting as a positive stop against thefurther movement of the back-frame. The pair of legs C being pivoted tothe back-frame at some distance above the upper surface of theseat-frame also act to furnish a considerable support to the back-frame,so that with such back-frame supported both above and below theseat-frame, as described, it will furnish a very strong support andwithstand great backward strains that may be imposed upon it by theuser.

When the chair is to be folded up into the position shown in Fig. 3, theback-frame D is to be turned forward, and as all of the connectionsbetween the parts A, B, C, and D are pivotal connections a turning onall such pivotal connections will. take place, with the result that asthe back-frame is turned to lie with the inner edges of its side barsagainst the edges of the short legs B the long pair of legs C will lieparallel with and against the shorter pair of legs B, with which legsthe back-frame D will also be parallel. When the chair is completelyfolded, the extensions of the side bars of the back-frame will be indirect line with the legs C and the seat-frameA brought into theposition indicated in dotted lines in Fig. 3. It will thus be seen thatnot only is a very strong and rigid folding-chair provided, but theconstruction is such that when the several parts of the chair arefoldedtogether they will occupy an exceedingly small space, the space, indeed,being, as is clearly apparent from Fig. 3, only equal to the combinedwidth of the back-frame and the pair of legs attached thereto.

That which I claim as my invention, and desire to secure by LettersPatent, is

In a folding chair including a back-frame having side bars provided withan intermediate offset, a seat-frame having its rear end pivotallyconnected to the side bars and arranged between the latter and below theOH- set, a pairof short legspivotally connected to the side edges'of theseatvframe in rear of the front edge of the latter, and a pair of longlegs pivotally connected to the sidebars of the back-frame at theoffset, and to the short legs, the long legsv being outside the shortlegs, seat-frame and side bars of the backframe, and the short legs,seat-frame and long legs when folded being in longitudinal parallelismwith the back-frame, said short legs contacting with one end of theback-frame for holding-the chair in an open position,
